  • A well organized system requirements provide a solid basis of achiving a successful project and are effective methods of communication among stakeholders. We illustrate and propose a 'System Requirement Development Framework' to develop correct requirements as a methodical approach. We first organize a 'Requirement Development Process' and then establish a 'Non-Functional Requirements Principle'. On these basis, we next propose a 'Requirement Development Guideline' from a perspective of 'Functional Requirement', 'Non-Functional Requirement' and 'Triage' in advanced stages. We also verify and evaluate the suitability of our proposed 'System Requirement Development Framework' by applying it to several projects.

  • In software engineering, requirement analysis is an important task throughout the process and takes up a high proportion. However, factors that fail to analyze requirements include communication failure, different understanding of the meaning of requirements, and failure to perform requirements normally. To solve this problem, we derived actors and behaviors using morpheme analysis and BERT algorithms in the Korean requirement document and constructed them as ontologies. A chatbot system with ontology data is constructed to derive a final system event list through Q&A with users. The chatbot system generates the derived system event list as a requirement diagram and a requirement specification and provides it to the user. Through the above system, diagrams and specifications with a level of coverage complied with Korean requirement documents were created.

  • Requirement engineering is being highly required for developing a new system nowadays because systems become more and more complex. System engineers require clear and distinct user requirement to avoid mistakes taking placing and mitigate the risks such over cost, schedule delay, and performance degradation during system engineering activities. The exact requirement elicitation make it possible to develop a systems to meet users need. In this paper, we presented a process and methodology to develop requirement for application to Automatic Train Control System. In the methodology and process presentation. we presented a key words to elicit requirement and showed how to analyse and validate the given requirement for ATC system.

  • Urban transit is system that offer target Performance and function because various lower part system such as vehicles, signaling, power supply, rail track is consisted as complex. It is important first of all that describe correctly system requirement until configuration of system, design, manufacture, installation and test verification so that the complicated urban transit system is to act safety and reliable and to display target Performance and function properly. The system requirement assist the system developer to comprehensive the performance and function of system in basic design. Therefore, In this paper wishes to study way to analyze system of system requirement and apply to Urban transit.

  • The HEMU-400X project starts at 2007. It is important first of all that describing correctly system requirement during configuration of system, design, manufacturing, installation and test verification so that the complicated high-speed electric multiple unit is to run safety and reliable and to achieve target performance and function properly. The system requirement assist the system designer to understand the performance and function of system in basic design. For this process, system engineer have to manage the system requirement. This paper proposes the management contents of system requirement such as change management, requirement traceability, etc, for HEMU-400X.

  • This paper describes system technical requirement development process from operational concept using computer-aided Systems Engineering tool(CASysE Tool-CORE). The army tactical missile system-ATACMS's technical requirements are developed by the process as a case-study The scope of the work is context analysis and requirement definition process. The proposed process is as follows. At first, an integrated architecture could be developed from the operational concept. From the integrated architecture a capability needs, which includes KPPs, are generated. And the capability needs expanded according to the Mil-Std-961D format. Lastly, a system technical requirement could be generated automatically from the CASysE Tool-CORE.

  • In this study, the design concepts for Intelligent Hospital are derived using the Quality Function Deployment(QFD) and System Requirement Analysis Method. First, requirements for important elements of Intelligent hospital are defined. Second, similar systems are compared and user requirement are refined. Through this process, operational requirement for Intelligent Hospital are defined by combining user requirements and similar systems. To analyze operational requirement, the QFD of the system engineering approach are implemented. Alternative design specifications are constructed by implementing the QFD results by building the Morphological Matrix. Various concepts that satisfy the system requirement are derived. Finally the best design concept are obtained using the Pugh concept selection matrix.

  • This paper describes a requirement architecture modeling for the front end of KT-1 export version requirement definition processes to construct SDS(system development specification). The requirement definition process is a highly conceptual process that is difficult to carry out. This paper focuses on how to perform the KT-1 export version requirements definition process including the integration of process, methods and tools for the front-end activity of requirements definition process. This requirement model is structured in four segments, including requirement layering, requirement categorization, life cycle stakeholder and requirement definition process using Computer-Aided Systems Engineering tool(CORE).
